V 11 Claims. This invention relates to a dump truck mounted on a tractor. More specifically it relates to a receptacle, which is mounted on a tractor along with a cotton picker unit and which re ceives cotton from the picker unit, and which can be swung across the tractor for dumping.

Normally, in tractor mounted cotton pickers,

' the cotton picked is conveyed from the picker unit to sacks, which are carried alongside of the tractor body. The removal of these sacks and the emptying of themfinto a larger receptacle is generally a diflicult and inconvenient operation. It Vhas been proposed to provide quite large receptacles on the tractor for receiving cotton from the picker unit, but the emptying of such a receptacle is alsoa problem.

An object of the invention is to mount a receptacleon a tractor so that it mal1 be easily dumped. l

Another object of the invention is to provide on a tractor, in connection with a vcotton picker unit, a receptacle which receives cotton from lthe picker unit and which can be emptied easily.l

Still another object of the invention is the mounting of a receptacle on a narrow bodied tractor, so that it may be emptied easily.

A further object of the invention is to mount a receptacle on a tractor in such a way that it is positioned on one side .of vthe tractor and swings to a dumping position about an axis on.Y

the other side of the tractor;

According to the present invention, a, receptacle is positioned alongside of the narrow bo'dy of a tractor having also a wide rear axle structure and a narrow front truck. 'I'he receptacle is arranged to swing about a pipe as anaxis to dumping position, which pipe is held on the o pposite side of the body of the tractor by means of supporting members extending from the tractor.A A cotton picker is also mounted on the tractor, but on the side opposite the receptacle,

and conveyors bring the cotton from the picker one side of the narrow body portion. is a cotton receptacle I4, which is formed of a framework I5 covered by a wire mesh I6. In one side of the receptacle is a sheet I1, which/aids the dumping of cotton from the receptacle when it 5 is swung to the dumping position, as shown in dotted lines in Figure 1. .If there were no sheet I1 at the particular side of the receptacle, but only wire mesh, dumping would be diflicult, since the cotton would stick to the wire mesh.

-Extending laterally from the ends of the receptacle are strap members I8 and I9, which are attached to plate and V-member 2|, inturn, attached, as yby welding, to a shaft or pipe 22 on the side of the narrow body portion opposite the 15 receptacle and paralleling the body portion. At its front end, this shaft 22 is supported by a diagonal member 23, in turn supported lby'upeV standing members 24 and 25 bolted to brackets 26 on opposite sides of a bolster portion 21 con- 20 nected with the front truck I3. These bracket members 26 are alsoattached to longitudinal channel members 28 attached atl their rear to the rear axle structure I2, said members 281con' stituting the tractor body' frame. As seen in 25 Figure 4, the rear end of the shaft 22 is supported by a cross channel member 29, in turn supportedrby upstanding members 30 and 3|. The upstanding member 30 `is secured to the one secured to a channel member 32 upwardly and outwardly of the other channel member 28 and carried at one-end on a iiange 33 of the r'ear axle structure by a plate 34, and at the front end by Y channel 28, and the upstanding member 3l is 30 the lower end of the diagonal member 23 with 35 the aid cfa bracket member 35. A brace 36 also helps -to support one end of the channel 29 and extends diagonally from said channel 29 by means of a plate connection .31 to a connection with the plate member 34 on the rear axle flange 40 33.` y

As previously stated, the receptacle is adapted .to be 'swung from the full line position to the y dotted line position in Figure 1 for dumping. This is accomplished by means of a power lift mechanism 38, which is not-shown in detail, since -it forms no part of the present invention and is fully described in Patent 2,109,668 to Edward A. Johnston et al., of March 1, 1938. Suf. fice it to say that the mechanism comprises essentially a cylinder 39 with a. push rod 40 ex-l tending into itand adapted to be moved in a direction out of the cylinder by means of uid pressure.

Thelower end of the power lift mechanism 38 55 Y Y, I

is pivotally supported, as at 4I. inthe bracket, and the rod 40 at fthe upper end of the litt mechanism vis pivotally attached to the plate 20. fixed to the'strap I8. A conduit 43 is connected with the power lift mechanism and adapted to' apply fluid pressure to themechanism from a vsuitable control (not shown) wlthinreach of the operator of the tractor.

To`one leg of the V-member 2| supporting the rear end of the receptacle is -secured apair of coil springs". A t' the other end of the springs abolt 41 is attached. The bolt 41 has a' spherical head portion 48, which rests in a correspondingly shaped bearing portion 49 fixed to the plate 31'. The springs 46 and bolt 41 tendv topull the receptacle away from. its dumping position.

When the receptacle is to be swung to dumping position. uid pressure is applied through the conduit 43 to the lifting mechanism 38, and the member 40 moves out of the cylinder: 39.

sition. At the start of the movement, the springs 46 assist the lifting mechanism in that they tend to moveto a dead centerposition on a. line `through the shaft 22. Beyond this position they resist thel lifting mechanism, tending to return to the dead center position. When thel dumping is completed, pressure to theliiting mechanism .is released, and the springs 46 pull the empty receptacle, at least, to a position over the 'shaft '22 from which gravity assists in bringing the rceptacle back to original loading position. The

spherical head 48- ofthe bolt 41, and the bearing ing forwardly and upwardly over the receptacle I4 from the conveyer 56. The conveyer 51 is sup- -ported by angle members 58 attached to the cross channel member 2 9. At the upper end of ,the conveyer 51, a spout 60 is pivoted on'members 6I, so'asrto extend over the receptacle I4. When thev receptacle is .tobe dumped, lthe spout is and novel structure has been obtained. Since so that the receptacle will clear it.v Y
